How We Select Winners
Users do not have to do anything other than select their numbers, the determination of the winner occurs completely on our end and you will be contacted if you win.
One of Zultifree's main features is the inclusion of guaranteed winner(s) in selected draws. A guaranteed winner means that the lottery will be won by someone, even if all the selected numbers of their ticket(s) are not matched.
Winning tickets are those deemed to be the “closest” to the winning numbers. This is done by calculating how many numbers a user's ticket matches with the winning numbers, and then calculating the circular distance to the remaining numbers. This is best explained with the use of a couple examples (both assume the lottery requires selecting 6 numbers between 1 and 45).
Example 1
If no one has won the lottery by matching all 6 numbers then the winner will be determined by closeness. If a user has matched 5 out of the 6 numbers correctly when no one else has then they will be deemed the winner. However, if 2 users have matched 5 out of 6 numbers then the closest is determined by calculating the distance between the remaining numbers. The table below will assist visualising the determination of the winner.
| Winning Numbers | 1 | 2 | 3 | 4 | 5 | 6 |
| User 1 | 1 | 2 | 3 | 4 | 5 | 10 (4 away) |
| User 2 | 1 | 2 | 3 | 4 | 5 | 11 (5 away) |
In this table we can see the winning numbers in the top row, user 1's numbers in the second row and user 2's numbers in the third row. Both users have correctly matched 5 numbers. To calculate who is closer we take the remaining number 6 and calculate the distance away each user's remaining number is. In this example user 1 is 4 away from 6 and user 2 is 5 away from 6. In this case user 1 is the winner and wins the lottery.
Example 2
An important factor is that the numbers are calculated on a circular distance. What this means is that for a lottery that requires selecting numbers between 1 and 45, number 45 and number 1 are only 1 distance from each other.
The following table shows what happens when circular distance is involved in the calculations when only 4 numbers have been matched.
| Winning Numbers | 1 | 2 | 3 | 4 | 5 | 6 |
| User 1 | 1 | 2 | 3 | 4 | 35 (15 away) | 20 (14 away) |
| User 2 | 1 | 2 | 3 | 4 | 17 (12 away) | 27 (21 away) |
In this instance user 1 wins because the distance of 15 + 14 = 29 is less than the distance of 12 + 21 = 33.
This is always automatically calculated to be optimised for each individual ticket to have the shortest distance.
